Regarding Web service Load Testing Plan and the Response generated

I am trying to create a rest web service Load Testing plan using Http Request with the following Details:
Service type : POST
host : rvoc4s45o8.execute-api.us-east-1.amazonaws.com
Port : none
path : /prod/api/cf/v0/session?req=true
I don't need to enter any port details. But in Neoload it's mandatory to give the port number while adding Http Request.
Expected URL To be Used : https://rvoc4s45o8.execute-api.us-east-1.amazonaws.com/pr...
But while using Neoload default port number is added in-between and the url looks like below:
https://rvoc4s45o8.execute-api.us-east-1.amazonaws.com:80...
Also i am not seeing any response for the web services while performing Testing. It's taking very long time.
Could you please help me to fix this issue
